The Research for Mechanical Properties after Fire of Concrete-Filled Steel Bridge Piers under Axial Loads

Abstract:

Objective. To analysis of steel concrete piers load - displacement curve of the whole process, to explore steel concrete piers ultimate bearing capacity and deformation effects at different temperatures. Method. Using ABAQUS finite element software for concrete piers steel axial compression nonlinear analysis, analyze the effects of different temperatures on the piers ultimate bearing capacity and deformation capacity utilization of the whole curve obtained. Results. As the temperature increases, the ultimate bearing capacity of concrete steel piers greatly reduced, the yield strength of the material is also decreased, reached the ultimate bearing capacity of the pier when the corresponding displacement is also significantly reduced. Conclusion. The temperature has a significant impact on ultimate bearing capacity and yield strength.
